The images in each eyepiece of the ophthalmic surgical microscope should overlap consistently. Among them is mainly binocular solid microscope, the overlap of images seen by both eyes of the surgeon should be good. Test method: use any 1 pair of eyepieces in the microscope, adjust its vision on the 0 position, to monocular observation. In the object position, put a piece of white paper with "crosshairs", adjust so that the "crosshairs" to clear. Move the white paper to locate the intersection of the "crosshairs" in the field of view of the eyepiece. In the "crosshairs" and the edge of the field of view of the four intersections, draw four lines, and then observe the other eyepiece should be located in the same position, both eyes at the same time, then should be completely overlapping.
 
Ophthalmic surgical microscope lighting there are two ways.
 
① internal light source - light source combination in the microscope, irradiation direction and the microscope coaxial, suitable for deep tissue illumination.
 
② external light source - the light source is located outside the microscope, divided into two types of coaxial and different axis lighting system. In order to make the object surface with sufficient illumination, the light source mostly uses halogen lamp or introduces optical fiber into the microscope and shoots to the operation field through the objective lens. Some surgical microscopes have both internal and external illumination systems, as well as illumination systems with slit lamp microscopes. High-quality ophthalmic operating microscopes have a fully coaxial light source.
 
Ophthalmic surgical microscopes require a clear and stereoscopic view of both the shallower or deeper intraoperative areas. In the case of shallow and deep range operation, no need to adjust the focal length. Therefore, the operating microscope should have a certain range of depth of field requirements. The main mirror is at 45° with the microscope body, while the assistant mirror is at 30° with the microscope body. When adjusting the focal length of the microscope, it should make the eyepiece clear at the field of view until.
